OBJECTIVES: To analyze the impact of anterior commissure involvement on local control, survival, and laryngeal preservation in patients with early glottic cancer (pT1a-pT2a) treated with unimodality laser microsurgical resection. STUDY DESIGN: Retrospective review of 263 patients with early glottic cancer treated between 1986 and 1996. METHODS: Data on local control and overall survival rates were analyzed and calculated by the Kaplan-Meier method; the larynx preservation rates were given absolutely. RESULTS: Among 158 patients presenting with T1a glottic cancer, the anterior commissure was involved in 28 cases; the 5-year local control rate was 84%, and the larynx preservation rate was 93%. In the 130 cases without anterior commissure involvement, the 5-year local control rate was 90.0% and the corresponding larynx preservation rate 99%. In the T1b category consisting of 30 patients, anterior commissure involvement was observed in 16 patients; the 5-year local control rate was 73%, and the larynx preservation rate was 88%. In the 14 cases without anterior commissure involvement, the 5-year local control rate was 92% and the corresponding larynx preservation rate 100%. Seventy-five patients had T2a glottic carcinomas, with normal vocal cord movement. The anterior commissure was involved in 45 cases; the 5-year local control rate was 79%, and the larynx preservation rate was 93%. In the 30 cases without anterior commissure involvement, the 5-year local control rate was 74.0% and the corresponding larynx preservation rate 97%. CONCLUSIONS: This study shows the effectiveness of laser microsurgery for early glottic carcinoma regardless of anterior commissure involvement at presentation. This method can be performed as an outpatient procedure, even when conducting reresections.
